Specification of Letters Patent.

Patented Oct. 9, 1906.

Application filed September 20, 1905. Serial No. 279,346.

To. all whom it. z t/t7 concern:

Be it known that 1, JAMES LYLE GLENN, Jr, a citizen of the United States, residing at Clarksville, in the county of Montgomery and State of Tennessee, have invented certain new and useful Improvements in Oorn-Shellbe a full, clear, and exact description of the invention, such aswill enable others skilled in the art to which it appertains to make and use the same.

This invention relates to corn-shellers of that class in which the grains of corn are rubbed from the cob by a toothed disk operating on the ear in connection with a suitable chute or frame which holds the ear in place against the disk.

The main objects are to simplify and im prove the general construction of machines of this class; to arrange the tensioning and adjusting devices in a position most convenient for attention-that is, around the diskshaft at the front of the machineand at the same time allow for shelling the ear of corn from the center of the disk; to conceal the tensioning-spring and protect it from exposure to the air to dispense with the usual connecting-bolts for holding the parts of the frame or hopper together and to provide means by which these parts may be instantly attached and detached, and to improve the clamping devices for aflixing the machine to the box, barrel, or other receptacle for shelled corn. These objects are attained by means substantially as .illustrated in the accompanying drawings, which form a part of this specification, and with reference to which the invention will be fully described and thereafter more particularly pointed out and defined in the annexed claims.

In said drawings, in which corresponding parts in the different figures are designated by the same reference characters, Figure 1 is a front view of a cor -sheller embodying my invention. Fig. 2 is a back view thereof. Fig. 3 is an inner face view of the front frame member. Fig. 4 is an inner face view of the rear frame member. Fig. 5 is a vertical cross-section through the mill, taken centrally and longitudinally of the disk shaft or axle. Fig. 6 is an enlarged detail vertical section through one of the clamps for attaching the machine to a box or receptacle for shelled corn.

A particular explanation of the drawings is as follows:

of a being ers and I do hereby declare the following to I ried up said chute d d adapted to engage VlOeS BIG The illustrated machine is of the light hand-operated style, such as usually employed for farm and domestic purposes, and is adapted to be mounted on the upper edge box or receptacle A for the shelled corn secured thereto by the clamps B. The frame of the machine is in twov parts C and D, formed at their upper ends with the usual confronting parts of the hopper E for receiving the ear of corn as it is fed to the toothed disk G.

The part C of the frame is shown as j a yoke comprising the legs 0 and cross-arm c, from the front of which projects a cylindrical boss or sleeve I, adapted to receive the shaft H of the toothed disk G. Said shaft is shown provided with a crank J forrotating the disk; The other part D is the usual shell or hopper member for holding the ear of corn in contact with the toothed face of the disk. This shell is formed with the parti-tubular chute d, extending down from the hopper E across the center of the face of the disk, for directing and controlling the ear of corn while it is subjected to the shelling action of the disk. Said shell D has also. atits lower portion an inclined chute d, against the base of which the cob abuts on its downward movement, so that as the butt-end of the cob. is carried laterally under the axis of the disk the cob will be turned at an angle and care and ejected. in the usual way from the machine through the opening at its upper part.

For the purpose of immediate attachment or detachment of the parts 0 and D one of such parts, here the member D, is formed with inwardly-offset depending lugs or pins in sockets c therefor in the other part 0. Two of such coactive deprovided at opposite sides of the hopper E, shown provided at the opposite sides of the lower portions of the members C and D. The sockets c are formed beneath vertical opensided slots or recesses 0 In placing the parts 0 and D together the depending pins d are brought into the slots or recesses 0 thus re '1 istering with the proper sockets, and the member D is then simply allowed to drop to engage the pins in the sockets 0 Thus the parts of the frame may be instantly attached or detached without the use of fasteningbolts or other manipulative devices common to machines of this character. The shaft H of the shelling-disk is inserted from the inner I side of the frame member G into the sleeve I,

while two additional devices are 'project at each side of the shaft.

whose bore is larger than said shaft. After the shaft is inserted into the sleeve a cotter pin or screw it is inserted crosswise through the shaft, being entered through a small oilhole 5. in the sleeve or hub 1 near the crossarm 0 and screwed. into a registering hole h in the shaft, so that the ends of said screw This screw it limits the inward movement of the shellingdisk by abutment against an interior shoulder or reduced part kg of the sleeve 1, said reduced part being in or near the cross-arm c and constituting an inner bearing for the axle. Surrounding the shaft within the sleeve I is a spiral spring K, shown having detachable runners or caps lc at its ends. The inner one of said caps 1c bears against a suitable shoulder or other abutment on the axle and yieldingly forces the shelling-disk inward, while the outer cap or runner bears against the inner end of a sleeve-nut L, which fits over the shaft and is screwed into the sleeve 1. This sleeve-nut L compresses the spring K, and thus provides the necessary tension for forcing the shelling-disk yieldingly inward, and. adjustment of said nut varies the tension of the spring. The runners 7c of the spring allow the spring to revolve around the shaft or axle. The bearings for the shaft are in the reduced bore kg at the inner end of sleeve 1 and in the sleeve-nut L, screwed into the outer end of said sleeve 1. A lock-nut M is screwed exteriorly on the sleeve 1, which is exteriorly threaded-oppositely to its interior threads. The purpose of the nut M is to lock the adjusting-nut L. Thus the spiral spring and adjusting-nut are arranged around the hub and axle at the front of the machine, the most convenient position for attention necessary to these attachments. The concealment of the spiral spring in the hub greatly adds to the appearance and at the same time allows the spring to be kept well oiled and prevents loss of elasticity by rust and exposure to the atmosphere. The construction and position of the different parts of the machine allow the ear of corn to be shelled in the c nter of the disk and also directly at the cente. of the axle, thereby preventing side thrust and friction at the hub.

Any suitable means may of course be adopted for securing the crank J to the shaft or axle. For example, the head of the crank may have a square or polygonal opening to means of a screw-bolt fitthe correspondingly-formed end over the shaft; but in the illustrated machine said crank J is shown attached to the axle by screwed into threaded openings in the head of the crank and in the shaft, the screw-bolt being made sufficiently long to pass through the head of the crank and through the axle and into the crank again, thereby securely fastening the crank to the axle.

or shelled-corn receptacle the lower ends of the legs 0 are shown roughened, as usual, to grip against the inner side of the box, whose upper edge supports the lugs 0 and the outer side of the box is gripped in the usual manner by the clamps B, through each of which passes a suitable clamping-bolt 1), connected with the frame. As an improved means for tightening and locking the clamps a wing-bolt bis passed loosely through each clamp and is screwed on the clamping-bolt I), while a thumb-nut b is screwed on said wing-bolt b, placing the clamp between said thumb-nut and head of the wing-bolt. To tighten the clamps, the wingbolts b are screwed on the clamping-bolt b until the clamps are tight, and then the thumb-nuts b are screwed on the wing-bolts until they come in contact with the clamps. The wing-bolt b can be taken off of the belt I) only by detaching the thumb-nut b and turning the wing-bolt to the left. Hence the turning of the wing-bolt b to the left when attached to the thumb-nut b draws both of them perfectly tight against opposite sides of the clamp B. Therefore they cannot be loosened from the clamp except by turning the thumb entirely off the wing-bolt by a left-hand turn.

The construction illustrated is of course susceptible of various modifications in details, general form of the frame members, and other parts, &c., and hence it will be understood the invention is not limited to the specific construction shown and described.

Having thus fully described my invention,

what I claim as new, and desire to secure by Letters Patent of the United States, is'
